Guys I know it's well done and all but it's a hoax and a half...
http://urbanlegends.about.com/librar.../aa100400a.htm
keep in mind that "test tube" babies don't acutally grow up in a test tube... they're concieved there and moved to a working uterous...
With out something for the ambilical cord to attach to the fetus will NEVER get any nutrition...
It's not currently possible...
they also have some stuff on the site about "nanodocs" which are allegedly little robots that monitor your health from the inside...
Now these ARE being worked on but they are in a purely conceptual state of development at this time...
it's a very well done hoax but it's faker than a 3 dollar bill.
